Title: Burst switching system
Inventor: ITO KAZUHIKO
IPC: H04Q11/04
Filed: 1985-03-14
Abstract: PURPOSE:To let the terminal equipment autonomously execute multiple separation of the communication channels by executing the reception or transmission of data when the communication channel number allocated to itself and the value of counting coincide with each other. CONSTITUTION:Respective one of line circuits 131-13n counts, by its counter, the channel number of each frame of the reception/transmission processing through the communication channel allocated by a control part 15 (in the figure, for instance, channel 0 is allocated to the line circuit 131 and channel 2 to the circuit 132), to enable the burst switching of the communication. First, a frame signal which shows the head of a frame is supplied to all the line circuits, and counters 220-2231 respectively provided in the line circuits are reset. Each line compares the counting of the said counter with the order of the channel its own equipment is to use. And if they coincide with each other, the data communication is abled. The figure shows a case the line circuit 130 coincides with a number '0', and is able to communicate.

Title: Magnetic disk device
Inventor: MARUWAKA TATSUFUMI
IPC: G11B21/02
Filed: 1990-03-01
Abstract: PURPOSE:To reduce the occurrence of dust by forming a step part for positioning an arm spacer on an arm cylinder inserting side of a magnetic head arm and forming an inner diameter of the arm spacer to be positioned by the step part not to come into slide contact with a circumferential surface of the arm cylinder. CONSTITUTION:This device is constituted in such a manner that the head arm 1 is formed to have approximately the same inner diameter not to generate backlash at the time of insertionally fitting to the circumferential surface of the arm cylinder 3, whereas the positioning of the arm spacer 2 is not performed with the circumferential surface of the arm cylinder 3 but an inner diameter surface 1a of the step part formed on the head arm 1. Consequently,the inner diameter surface 2a of the arm spacer 2 is formed not to come into slide contact with the outer circumferential surface of the arm cylinder 3. By this method, since friction contact caused at the time of inserting the arm cylinder into the head arm, etc., is reduced, the occurrence of dust when the arm spacer is inserted is reduced, and the reliability of the magnetic disk device is thus improved.

Filed: 1985-03-14
Abstract: PURPOSE:To enable the cooling of an element by a common cooler, by arranging a CO2 laser detector and an image pick-up HgCdTe element in the detector of an integral type infrared receiving optical system. CONSTITUTION:A SO2 laser oscillator 16 outputs laser beam 17 simultaneously with excitation and laser transmitting beam is emitted toward an external target fro a laser transmitting optical system 18.

The reflected beam from the mirror 24 is again reflected by an interlace mirror 25 and the reflected beam is allowed to irradiate the HgCdTe detector arranged in a detector 26 and detected. Further, a cooler 39 cools the Dewar mechanism of the detector 26. The optical system 21 has function for passively introducing infrared radiation energy in the visual field containing the target and this energy is guided so that a focus is formed to the image pick-up HgCdTd element arranged to the detector 26.

Title: Rotary head drum device
IPC: G11B15/61
Filed: 1992-03-10
Abstract: PURPOSE:To diminish the spacing between a tape and a head and to provide the stable contact of the tape and the head by using a porous material for the blank material of a rotary drum, thereby decreasing the floating amt. of the tape from the rotary drum. CONSTITUTION:This rotary head drum device consists of the rotary drum 1 consisting of the porous material and a stationary drum 2 below this drum. The magnetic head 3 is mounted on the drum 1 so as to project slightly from its outer peripheral surface. The porous material is constituted by packing spherical metallic powder 11 into the material and the central parts are formed as holes 12. Air can pass this rotary drum 1. Then, the air advancing into the spacing between the drum 1 and the tape 4 is compressed between the drum 1 and the tape 4 and is then escaped through the holes of the wall surface of the drum 1 in an arrow 5 direction to the inside of the drum 1. As a result, the contact of the head 3 and the tape 4 is improved.

Title: Moving-bed filter
Inventor: KATAGAI NOBUYOSHI
IPC: B01D24/00
Filed: 1980-04-16
Abstract: PURPOSE:To increase the throughput per unit area of the installation floor space, by constituting the structural elements of the filter in a two-dimensional bilaterally symmetric construction, and by two-dimensionally moving the sand and water. CONSTITUTION:The influent water is introduced from the inlet pipes 1a, 1b installed in the lower part of the left and right walls of the filter shell 6 through the underside of the influent guide plate 15 into the filter bed; the water goes up while being filtered by the filter medium 3, and the filtrate is collected and discharged through the filtrate discharge pipe 2. The filter medium 3 goes down, arrives at the hopper 4, and is transmitted from the bottom air-lift box 5 to the sand-washing soil water separator 8 through the sand air-lift pipe 7; the sands caught by the filter medium 3 is freed from the filter medium 3 in the separator 8. Although the filter medium 3 goes down, since the water level of the filtrate discharge pipe 2 is kept higher than the overflow weir 13 of the sand-washing soil water in order to make a part of filtrate go up, the filter medium 3 is further washed, and the sand-washing soil water containing sands overflows the overflow weir 13 and is discharged from the sand discharge pipe. While the filtration is thus operated, the sands and water move in two dimensions because the respective structural element is arranged in bilateral symmetry.

Title: Image forming device
Inventor: SANO YOSHIHISA
IPC: G09G3/20
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent deviation in the track of an emitted electron by suppressing the electrification of a spacer constituting an image forming device which uses a cold cathode electron source. SOLUTION: The driving time of the element closest to the spacer is divided. Concretely, the driving time (t) (100 μs) needed in one frame is equally divided into three and the elements closest to the spacer are driven sequentially with timing shift of 1/180 (sec). The discharge current from the element which is driven is up to 1 μA for each element. Consequently, the maximum value ΔVsat of the electrification potential in the center of the spacer is about 50 V. In this case, the maximum value ΔVsat of the electrification potential in the center of the spacer is smaller than that when the driving time is not divided as before. That is, the ΔVsat is suppressed by about 20 V when the driving time is divided into three than when not. Here, the driving time is equally divided into three, but some effect is obtained even by 2 or >=4 division.

Abstract: PURPOSE:To detect even a small defect with high accuracy by compensating the detected signal of a bottom face echo by the detected signal of a surface echo, and deciding the state of a defect, based on the compensated detecting signal of the bottom face echo. CONSTITUTION:An ultrasonic pulse is made incident on an object material to be inspected 12, an echo which is generated by its reflection is detected, and the detected height S of a surface echo 20, and the detected height B of bottom face echoes 21-33 are detected. In this state, in order to compensate the detecting signal of the bottom face echo by the detecting signal of the surface echo, the S/B or B/S of each signal height S, B is calculated. In this case, the compensation can be executed by only taking the ratio, therefore, a bottom face echo signal can be compensated by a comparatively simple procedure. A threshold level is provided against the variation quantity of a value of a compensated bottom face echo signal B/S or S/B, and when a variation exceeding its threshold level is generated, it is decided that an internal defect exists in the object material to be inspected. Also, when the threshold level is not provided, the value itself of the calculated S/B or B/S is used as an index for deciding the state of the internal defect of the object material to be inspected.
